Lymphocytes and macrophages frequently are observed infiltrating Hodgkin's Disease lymph nodes, correlating with a favorable prognosis in this disease (Proc. Am. Assoc. Cancer Res. 12: 43 (1971).
Lymph nodes positive for neoplastic cells from untreated patients
with the nodular sclerosis type of Hodgkin's Disease were fixed within
30 seconds after surgical removal and were examined by high-resolution
electron microscopy. Lymphocytes or macrophages tightly opposed to neoplastic
Reed-Sternberg cells correlated directly with cytotoxicity within such
neoplastic cells. Three additional types of macrophage activity were observed:
(1) macrophage phagocytosis of collagen fibrils, with desmosomes
shared between participating macrophages;
(2) macrophage endocytosis, especially when adjacent to activated
lymphocytes, and
(3) macrophage phagocytosis of lymphocytes in the absence of desmosomes
or endocytosis.
These studies indicate that immune lymphocytes in Hodgkin's Disease may be directly attacked by macrophages in-vivo, perhaps after such lymphocytes acquire Hodgkin's tumor antigen on their cell surfaces via specific lymphocyte immune interaction with circulating free tumor antigen. Macrophage phagocytosis of lymphocytes may correlate with the absolute lymphopenia and immunosuppression often observed before therapy of patients with advanced stages of Hodgkin's Disease.
